Branding is staged by channel, so that you can test your branding before shipping it to
customers. If you remove the branding & leave a comment in the CSS/* show minimal */ you’ll get a minimalist version of Replicated UI:

By default, existing vendors will have the traditional purple, orange, teal colors set as
their default CSS for all channels. Existing client installations will fallback to the
traditional colors if no CSS is available.

Updates to the CSS are applied at installation (new install), when a customer updates to a
Replicated brand-able version (1.2.73 or newer) and then anytime an app update is applied. CSS updates are also applied during a license sync.
